Design Engineer--Allen Roy serves as the Engineering and Logistics lead at Tactical Baba, bringing a disciplined, mission-focused approach shaped by both military service and decades of technical experience. A veteran of the United States Marine Corps, Allen served as an equipment technician with extensive weapons training across multiple platforms. His time in the Marine Corps instilled a deep respect for firearms safety, reliability, and performance under stress—principles that directly align with Tactical Baba’s training philosophy.

With over 20 years of technical experience and more than a decade spent in engineering roles at industry-leading manufacturers, Allen has developed a strong command of how complex systems are designed, tested, and sustained.
